WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a
safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRC/VSC system is operating. Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist co ntrol is not intended to hold the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist con-trol to hold the vehicle on an incline, as doing so may lead to an accident.
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRC/
VSC systems off unless necessary. Trailer Sway Control is part of the VSC syst em and will not operate if VSC turned off or experiences a malfunction.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tire s are inflated to the recommended tire infla-
tion pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional for further information when replacing tires or wheels.

WARNING
■Handling of tires and the suspension
Using tires with any kind of problem or modif ying the suspension will affect the driving assist systems, and may cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations. Depending on many factors such as the conditions of the vehicle, trailer, road surface,
and driving environment, the Trailer Sway Control system may not be effective. Refer to your trailer owner’s manual for informatio n on how to tow your trailer properly.
■If trailer sway occurs
Observe the following precautions. Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
●Begin releasing the accelerator pedal immediately but very gradually to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize. ( P. 238)

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents. Failure to do so may result in a loss of vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the
snow tires being used.
●Use snow tires on all, not just some wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents. Failure to do so may result in the vehicle being unable to be driven safely, and may cause death or serious injury.
●Do not drive in excess of the speed limit sp ecified for the tire chains being used, or 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle control is main-
tained.
●Do not use the LKA (Lane-Keeping Assist) system. (if equipped)

●Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. And, utility vehicles have a significantly higher rollover
rate than other types of vehicles.
●An advantage of the higher ground clearance is a better view of the road
allowing you to anticipate problems.
●It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.
Utility vehicle precautions
This vehicle belongs to the utility vehicle class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity.
Utility vehicle feature
WARNING
■Utility vehicle precautions
Always observe the following precautions to minimize the risk of death, serious injury or damage to your vehicle:
●In a rollover crash, an unbelted person is significantly more likely to die than a person
wearing a seat belt. Therefore, the driver and all passengers should always fasten their seat belts.
●Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may re sult in loss of control or vehicle rollover causing death or serious injury.
●Loading cargo on the roof luggage carrier wi ll make the center of the vehicle gravity
higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt maneuvers, otherwise it may result in loss of control or vehicle rollover due to failure to operate this vehicle correctly.
●Always slow down in gusty crosswinds. Because of its profile and higher center ofgravity, your vehicle is more sensitive to side winds than an ordinary passenger car.Slowing down will allow you to have better control.
●Do not drive horizontally across steep slopes . Driving straight up or straight down is preferred. Your vehicle (or any similar off- road vehicle) can tip over sideways much
more easily than forward or backward.

travel.
●Respect private property. Get owner’s permission before entering private
property.
●Do not enter areas that are closed. Honor gates, barriers and signs that
restrict travel.
●Stay on established roads. When co nditions are wet, driving techniques
should be changed or travel delayed to prevent damage to roads.
Off-road driving
WARNING
■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle:
●Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger- ous places.
●Do not grip the steering wheel spokes when driving off-road. A bad bump could jerkthe wheel and injure your hands. Keep both hands and especially your thumbs on the outside of the rim.
●Always check your brakes for effectivene ss immediately after driving in sand, mud, water or snow.
●After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody. Clear off any such matter from the underbody. If the vehicle is used with these materi- als trapped or adhering to the underb ody, a breakdown or fire could occur.
●When driving off-road or in rugged terrain, do not drive at excessive speeds, jump, make sharp turns, strike objects, etc. This may cause loss of control or vehicle rollover causing death or serious injury. You are also risking expensive damage to your vehi-
cle’s suspension and chassis.
